TO ALL WHOM IT MAY CONCERN;

Be it known that I, JOHN H. BEAUREGARD, of Kingsbury, in the county of Washington, in the State of New York,have invented a new and improved Heep-Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specication.

This invention relates to an improved hasp-lock, whereby greater simplicity and security are obtained than are afforded by the hasp-locks heretofore in use. n

It consists mainly in the eontrivances for locking the bolt when shot into the staple, andv which cannot then be unlocked, even with the proper key, without first performing an independent operation, which consists in thrusting the bolt yet further forward in a direction opposite to that `in which. it must be moved to release thehasp. i I

In the accompanying drawings- Figure l is a front view of my improved hasp-lock, showing the same boltedLa-nd A Figure 2 is a detail view thereof, showing the hasp bolted but not locked, the dotted lines showing theA position of the parts when thebolt is locked and thrust forward to enable it to be unlocked,

Figure 3 is an isometrical view of the key, which I prefer to use to lock and unlock the'bolt, though any other form of key might be used. I I

Similar letters of reference indicate corresponding parts.

B is the hasp, which I prefer making of wrought iron, and which is provided with a circular extension or plate, B B', which forms'the bottom plate for the reception and attachment of the working parts, and forming, with the rim or wall S and top plate T, a. suitable box to contain said working parts A is the bolt, passing through slots S" S S S in the rim or wall S, and is cut out at a a to enable the locking-circle to be received at a', and so preventing the withdrawal of the bolt.

P and 0 are ears or stops, attached to the upper and under edges of bolt A for the purposes presently described. l

l N N N are guides, holding the locking-cirele D in place 'to the wall S, N N" serving also as head-blocks for the springs E E and engaging-lever L. I

The locking-circleD carries, on 'a portion of its circumference, the internal cog V, which engages in the segmental ratchetwheel C, operated'by the key X, iig. 3, by which the end of the locking-circle is thrown across the shoulder a of the bolt A. Y

W is a tooth, set near the opposite end of the locking-circle; and when the bolt has been shot forward it is made to engage with the tooth Z, operating .the segmental wheel- C With the key, S0 @S t0 thlOW the Dd 0f circle D behind the shoulder a,) and being so engaged, prevents the circle D from being operated by the seg-4 lmental wheel to withdraw the circle D from a', and vthus prevents the bolt from being unlocked.

The spring E, set in the head-blocks N', presses against the engaging-levrer L, holding it home to the,

locking-circle D. The spring E', set in the head-block N, presses the boltA against the upper portion of the slots S S S S. K,

A handle or knob, H, connects by the pin M, (which works back and forth -in a slot in the top plate vT,) and operates the bolt A. l' The bolt being thrown forward, the key is inserted in the ratchet-wheel C, and turned in the direction of the arrow, throwing the end of the'locking-circle behind the shoulder a', and drawing' back the tooth W until it passes the end-ot' the tooth Z,.when the spring E, pressing up the engaging-leverL, 'the tooth langages in W',

and prevents the end, cl, of locking-circle D from being withdrawn. Y Y

To unlock the bolt, an upward and forward'pressure must now be employed at a, whereby the outer end of bolt A is depressed, and the ear P, which, in looking, by striking against the wall' S, prevented the bolt from being shot too far, enters the Slot S', and the ear O, now striking against said wall, prevents the bolt from being overshot. As the bolt is pushed forward, the pin K moves the arm of lever L into the position shown by the dotted lines, releasing the tooth W, and enabling the end, d, of locking-circle D to be retired from the shoulder a', by the key operating the ratchet-wheel C, and 'the bolt is then withdrawn from the hasp by simply drawing it back by the knob or handle H.

The locking-end ofthe bolt A may be'inade with a semicircular section for readiness of adjustment to any kind of stapleY The key-hole Q may be cut in top plate T in a position different from that in which the key has to be inserted in thc wheel C, so as to render it necessary to be turned; beneath the plate T, and increase the diiculty of unlocking the bolt on the part of a person unacquaintcd with the mechanism. l

A thumb-piece or button, R, may also be inserted on the end of bolt A, and Works in slot S'" as a blind to persons tampering with the lock, as they would be sure to press on the thumb-piece or button, under the notion that it must have something:r to do with enabling the bolt to be unlocked.

The top plate T and rim or Wall S may be cast in one piece, and the working parts being attached in place on thewroughtiron bottom plate B', the top plate and Wall may then be-secured over them upon the bottom plate B. Y l

Another great advantage which my improved hasp-lock presents is, that water can rarely get inside to rust the Working part-s, as generally happens in locks attached to out-buildings; while if the lock be attached hanging downwards, and water should at any time get in, it will run out at the slot S in rim or wall S.

When'the lock is set horizontally, a small hole or slot-may be pierced in the lower portion of the Wall or rim S to'effect the same object.

It will be seen that when the boltA is unlocked, it is drawn back and forth at pleasure, and serves, as any common hasp or bolt, to keep the door'to.

Having thus described my invention, what IY claim as new, and desire to secure by Letters Patent, is-

l. The locking-circle, constructed with the internal cog V and the tooth W, in combination with bolt A and lever L, substantially as and for the purpose described.

2. The bolt A, fastened substantially as described, and provided with the ears or stops O P, as and for the purposes substantially as described.

3. The pivoted engaging-lever L, with tooth Z, in combination with the locking-circle D, pin M, and bolt A, substantially as and for the purpose described.

The above specification signed by me, this`eleventh day of March, 1868.
